AI is advancing faster than our ability to manage it. We still have the opportunity to build the societal & technical guardrails needed to keep people, institutions and democracies safe—we shouldn't let it pass us by. Interview with @elconfidencial.bsky.social www.elconfidencial.com/tecnologia/2...
elconfidencial.com
Yoshua Bengio ayudó a crear la IA. Ahora lanza su aviso más serio: "No estamos preparados"
Considerado uno de los pioneros de la IA moderna, Yoshua Bengio lleva años alertando de los riesgos "catastróficos" si esta tecnología no se controla y regula. Su preocupación, igual que el poder de la IA, no ha hecho más que aumentar
